Pistol Packin' Mama (1943)

Two tuneful gamblers gambol across the country in a struggle for the money they need to run their respective casinos. It all begins when gangsters oust a gambler from the Big Apple. In need of quick cash, he goes to Las Vegas and enters a casino owned by a tough but pretty young woman. Cheating like crazy, the gambler breaks the house back and takes his considerable winnings back to New York to open his own casino. The woman is in hot pursuit and eagerly plans to turn the tables in her favor.
